I recommend a Winegard HD7694P outside on the mast. Put a distribution amplifier Channel Master CM3414 four way distribution amplifier inside the house. Aim the HD7694P at about 60 degree magnetic compass. Use all new RG-6 coax from the antenna to the distribution amplifier. From each output of the distribution amplifier , a coax goes to a Tv/converter box. Any outputs the of distribution amplifier that are not used should have a 75 ohm terminator so the system is balanced. The Tv stations in green are easy to receive with strong signal strength. The Tv stations in green are in one direction except KPXM UHF 40 ION Tv that is on the side of the HD7694P antenna. However the signal is strong and by turning the HD7694P antenna more in the direction of KPXM , I think it will be received with out having to much reduction in signal strength of the other stations. Here are places to buy Tv antennas and etc. ,
